NPZ AND NPZD MODELS IN A SIMULATED COASTAL UPWELLING SYSTEM

Simple NPZ (nutrient-phytoplankton-zooplankton) models and NPZD (nutr.-phyto.-zoo.-detritus) models are coupled to physical circulation models for idealized coastal upwelling situations. One upwelling calculation utilizes a 2-D onshore-offshore slice formulation. Another upwelling model contains smoothed, idealized bottom and coastal geometry in a 3-D computation. Comparing results for the NPZ and NPZD calculations, we find realistic biological parameter ranges for which calculated abundances differ little. We also find realistic ranges for which results disagree significantly. This is especially true when stage-structure is introduced into the Z (zooplankton) component. Causes for the disagreements (and agreements) between the two models are advanced.
